Non-woven Geotextile
Geotech is a product of Wulwith International Co., Ltd., offering synthetic materials designed for protective applications and engineering solutions, particularly in environmental engineering.
Manufactured in a standardized production facility, Geotech is produced under a computerized quality control system to ensure consistent quality and performance. The manufacturing process focuses on key material properties and overall efficiency, providing reliable and effective solutions for a wide range of engineering applications.
Geotech is made from Polypropylene (PP) or Polyester (PET) fibers in a Needle-Punch Nonwoven structure. It is available in widths ranging from 4.0 to 5.5 meters and can be manufactured with weights from 100 to 1,500 g/m².
Geotech is designed for a wide range of engineering applications, including soil separation, soil protection, filtration, erosion control, drainage, and material reinforcement.
Benefits
- Reduces construction and maintenance costs
- Easy and cost-effective installation - Available in widths of up to 5.5 meters, reducing the number of joints and overlaps required during installation.
- Environmentally friendly - Helps reduce the use of natural gravel and sand, contributing to the conservation of limited natural resources.
Specification of PP Geotextile
Geotech geosynthetic materials used in hydraulic and civil engineering structures can help improve the efficiency, stability, and overall performance of these structures. Geotech can be applied to a wide range of engineering applications.
Main Functions
- Separation
- Protection
- Filtration
- Erosion Control
- Riverbank Protection
- Reinforcement
General Applications
- Improving the stability of structures built on soil
- Protecting riverbanks from erosion
- Providing filtration and drainage layers
- Protecting geomembranes from tearing and puncture
- Reinforcing soil in road embankments, slopes, and retaining walls
1. Material Separation
Problem
When constructing and compacting pavement or fill materials over soft existing soil, the materials can become mixed and interpenetrate. This can reduce soil stability and affect the load-bearing capacity of the structure.
Solution
Geotech is installed between the pavement or fill layer and the existing soil to separate the different material layers. This prevents intermixing and helps maintain proper compaction and stability of the existing soil.
Applications
- Roads and temporary roads
- Railway projects
- Airports and parking areas
- Earth dams
- Embankments constructed over soft soil
2. Geomembrane Protection Against Puncture and Tearing
Problem
Geomembranes can be easily punctured or torn by sharp objects or other materials. Damage can occur when the geomembrane is subjected to heavy loads during installation or subsequent construction activities.
Solution
Geotech is installed as a protective layer beneath the geomembrane. It helps prevent sharp objects and other materials from puncturing or tearing the geomembrane, improving its durability and protection.
Applications
- Landfill sites and wastewater treatment ponds
- General water ponds, decorative ponds, and agricultural ponds
- Water reservoirs
- Earth dams and irrigation canals
3. Filtration and Drainage
Problem
Filtration and drainage systems can become clogged when soil particles, gravel, stones, and other fine materials migrate into the drainage layer. This can reduce the efficiency of the filtration and drainage system.
Solution
Geotech is installed between the drainage gravel layer and the soil layer to prevent soil particles from entering and clogging the drainage system. This helps maintain effective filtration and drainage performance.
Applications
- Roadside drainage systems
- River, canal, and coastal erosion protection
- Drainage systems for agricultural areas, golf courses, sports fields, and gardens
4. Erosion Control
Problem
Soil erosion can occur along riverbanks, coastlines, around bridge foundations and piers, and beneath wire mesh gabions. Water flow and tidal movement can cause soil particles to move, resulting in erosion and loss of soil.
Solution
Geotech can be installed together with rock, concrete blocks, and gabion structures to help control erosion. The Geotech layer helps retain soil particles and prevents them from being washed away by water flow.
Applications
- Riverbank and coastal protection
- Bridge foundations and piers
- Gabion structures for soil protection
5. Material Reinforcement
Problem
Slopes without adequate reinforcement can become unstable, resulting in soil erosion and failure along the slope surface.
Solution
Multiple layers of Geotech can be installed during slope construction to reinforce the soil and improve slope stability. This helps create safer and more stable slopes.
Applications
- Road embankments
- Reinforced retaining walls
- Slopes, roads, and bridge structures
